Abstract:
An experiment was carried out to investigate the influence of pruning, nutrition and paclobutrazol on the availability of nutrients in soil and leaf for two consecutive years (2017-18 and 2018-19) in the established mango orchard on 7 years old Alphonso mango trees and maintained at 5 X 5 m spacing at Regional Horticultural Research and Extension Centre, Bengaluru. Among the eleven treatments T4 showed best results. Higher readings for soil nitrogen (413.40 kg/ha), soil phosphorus (48.10 kg/ha), soil potassium (290.03 kg/ha), soil calcium (7.23 meq/100g), soil magnesium (3.61 meq/100g), soil sulphur (13.92 ppm), leaf nitrogen (1.28%), leaf phosphorus (0.20%), leaf potassium (1.04%), leaf calcium (0.63%), leaf magnesium (0.56%) and leaf sulphur (0.11%) are recorded with pruning at 10cm length along with PBZ @ 0.75 g a.i./ m canopy diameter, 75% of RDF, 10 kg vermicompost, 20g of AMC and mango special spray.
